摘要:
In a shockwave system with a shockwave source for treatment of a patient with shockwaves, a control and evaluation unit for evaluating an input signal supplied directly thereto that is correlated with a blood pressure value of the patient determined during the treatment, and controls the shockwave source dependent on the input signal.
摘要:
In a method to determine an operating parameter of a shockwave source for the generation of a shockwave to disintegrate a calculus in a patient by a shockwave lithotripsy, a characteristic of the patient and/or of the calculus is determined before and/or during the shockwave lithotripsy and the operating parameter is automatically determined dependent on the characteristic. A device for determining an operating parameter of a shockwave source for the destruction of a calculus in a patient has an acquisition and control unit for determination and/or input of a characteristic of the patient and/or of the calculus, and for automatic determination of the operating parameter dependent on the characteristic.
摘要:
A therapy apparatus has a source of acoustic waves which propagate through a medium in the source, a setting arrangement by means of which a desired distance can be set between a body surface of a patient and a reference point of the source, and an arrangement for determination of the distance of the body surface of the patient from the reference point. The latter arrangement includes a sensor element that is contained inside the source and which can be displaced in the direction of the acoustic axis of the source. The sensor element is in at least indirect contact with body surface of the patient during the determination of the distance. The apparatus also has a display arrangement for providing a quantitative visual indication of the distance.
摘要:
A therapy apparatus has a radiation source and a base part standing on the floor of the treatment room, the radiation source being connected to the base part and the base part containing devices required for the operation of the radiation source. The base part has an upper part fashioned at least as part of a patient bearing assembly. At least one further part of the patient bearing assembly is attached to the base part, at least during operation of the therapy apparatus.
摘要:
An electrically driveable shockwave source for generating acoustic shockwaves of the type suitable for medical therapy, as a coil arrangement and a membrane disposed adjacent the coil arrangement. The membrane and/or the coil arrangement is formed by a multi-layer structure, with each layer having electrically conductive elements therein insulated from each other, in the form of electrically conductive sections in the membrane, or electrically conductive windings connected in parallel in the coil arrangement.
摘要:
A shock wave source of the type suitable for treating calculi in the body of a patient has a closed space filled out by a coupling fluid, as well as a hollow-cylindrical, air-filled space, centrally located in the shock wave head, which does not attenuate x-rays. The centrally located space allows for acceptance of an ultrasound locating system. It is covered on the application side by a flexible foil, providing for a shock wave head which is free from contamination of particles from the opening of the above mentioned space to the application surface of the patient.
摘要:
In a method to disintegrate a calculus in a patient by shockwave lithotripsy, a 3D image data set of the patient is generated in a first step; the shockwave lithotripsy is conducted in a second step; and first step and second step are conducted with an unchanged position of the patient. A lithotripsy system to disintegrate a calculus in a patient has a shockwave system to disintegrate the calculus and a 3D imaging system to generate a 3D image data set of the patient without movement of the patient.
摘要:
A medical-technical system workstation for open or minimally invasive surgery has a patient support mechanism and at least one medical device with at least one applicator connected to the medical device. The medical device is attached to the ceiling of a room containing the workstation, or in or at the patient support mechanism or in or at a unit that can be placed at the patient support mechanism.
摘要:
The invention relates to a method for stimulating bone growth in a mammal. The method comprises the step of exposing a bone zone where bone growth is to occur to cavitation for bringing forth haemorrhage and/or microfissures and/or to at least partially loosened bone chips at said bone zone.
摘要:
A therapy apparatus for treating a patient with focused acoustic waves has a source of focused acoustic waves which converge in a focus zone, and a locating system for locating a therapeutically relevant region of the body of the patient. The locating system has a graphic display for displaying an image of the therapeutically relevant region (S). The apparatus also includes control and circuitry mixing a properly scaled contour (C) of the focus zone within the respective image defining a boundary within which the acoustic waves do not fall below a threshold with respect to an acoustic characteristic. The controls can be used to set the size of the contour directly, or to set the size with respect to one or more selected acoustic parameters.
